A copy of JAMSCD4 sold on eBay on 25th October for £114 (with only one bid, apparently). The packaging looks rather odd: http://thumbs3.ebaystatic.com/pict/2804116847868080_1.jpg
First of all, it seems to have a large pink sticker over the top of the green "1" - and also appears to have a clear plastic inlay tray (with a green strip with white writing underneath it, through the plastic. It looks for all the world like a reissue - certainly not an original: no CDs I ever saw in 1989 had clear plastic inlay trays, and I've never seen a JAMSCD4 (just JAMSLP4s) that has a sticker. Sadly, the item is no longer clickable (eBay says it's been "removed") but if you check "completed items" and "KLF" in eBay it shows up if you filter by price. It's about halfway down the page.
From the tiny thumbnail image, it looks are rather snazzy item - but it no way like the original 1989 CD.
Thoughts, anyone?
